The flute has progressed over the years with regards to scale, pitch and response. Many modern flute makers employ new manufacturing techniques to ensure that all notes are stable and true to pitch. For many flutists, the third octave E natural can be challenging. Depending on the individual, this note may not be as stable as others. The split E mechanism provides a reliable solution for flutists seeking to improve the response of their third octave E.
The Split E mechanism can dramatically improve the response of high E. This mechanism divides the action of the upper and lower G keys, permitting the lower G key to close when high E is played. Closing the lower G key and fingering high E decreases venting and brings more stability to the note with a faster response. This mechanism employs a separate rod, adding a slight bit of weight to the flute. The split E mechanism must be made on the flute during manufacture.
